Advances in fuel cells EIS data analysis using the distribution function of relaxation times methods

Shweta Pal, Yoed Tsur

Abstract

Analyzing Electrochemical Impedance Spectroscopy (EIS) data measured on fuel cells is increasingly done by finding the Distribution Function of Relaxation Times (DFRT, also known as DRT). This has clear advantages in cases where the important loss mechanisms occur in series and at separable time constants. Then each peak may be attributed to a process, and its integral yields the effective loss associated with it. Recent advances in this field are briefly reviewed.
